EPECIPICATION forming partof Letters Patent No. 321,530, dated July 7, 1885.

Application filed April 14, 1884.

To all whom. it may concern.-

Be it known that I, F. F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massaehusetts,acitizen of the United States, haveinvented anew and useful Improvement in Heel-N ailing Machines,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, in which Figure 1 is a view of a portion of a National machine representing my invention, part in vertical section and part in elevation. Fig. is a section and plan on and below the line 00 x of Fig. 1. Fig. 3 is a view, part in elevation and part in vertical section. Figs. 4 to 13, inclusive, are detail views, hereinafter referred to. Fig. 14 is avertical central section of the top-lil'tholder plate and the top-lift holder.

This invention is an improvement upon that described in Letters Patent Nos. 252,215, 259,687, and 287,472; and it relates especially to means for providing the parts with automatic movements, and to various details of construction, as will hereinafter more fully appear.

. templet b with asleeve, I), which fits thereon.

The post is bolted to the bed-plate of the maehine. The shaft E connects the shaft of the revolving head a. with the nail-holder plate 0 by means of the bevel-gear 6, attached to the inner end of the shaft a, and the bevel gear 6' upon the shaft E, movable thereon vertically,

and held to the cross-head by the bracket 6 This connecting device is like that described in a pending application of J. XV. Soule. The

shaft,however,is carried down through the post I), and is automatically revolved by means of the cam-groovef in the cam-disk F,attached to the crank-shaft f lever f, pivoted at f, hav- (No model.)

ing the pinf, which enters the cam-groove f, the link f which connects the lever f with the lever f, which is pivoted to the stud g, which supports the ratchet-wheel G, which lever has the spring-pawl g, which engages with the ratch et-wheel G. This ratchetwheel is secured to the cog-wheel g on the stud g, which meshes with the gear-wheel H on the lower end of the shaft 13. This gear-wheel is supported by the arm or bracket 72-, and is splined on the shaft, so that the shaft may have a vertical movement therein.

It will readily be seen that upon the movement of the crankfthe ratchet-wheel is revolved by the cam a portion of a revolution, depending upon the throw of the cam and of the leverage employed and the size of the ratchet and gear wheel 9' in relation to the gear-wheel H. XVhen three reciprocations of the machine are employed for attaching the heels-namely, one to drive the awls, one to drive the drivers, and one to spank-*thenailholder plate is moved a third of a revolution each reciprocation.

In the drawings, I have represented a cam and connecting devices adapted to revolve the nail holder plate a third of a revolution for each reciprocation, and the various positions of the plates in relation to the awls, drivers, and spanker-blocl; are represented in Figs. 5 to 10, inclusive. Fig. 5 represents the position of the nail-holder plate upon the reciprocation of the awls. Fig. 7 represents the position of the nail-holder plate upon the reciprocation of the drivers; Fig. 9, its position upon the reciprocation of the spanker; and, likewise, Figs. 6, S, and 10 represent the various positions of the awls, drivers, and

spankers at these various intervals in the revolution of the nail-holder plate.

To prevent the momentum of the shaft and its attachments from throwing it farther than is desirable, I have secured to the shaft E, below the gear-wheel H, the brake-wheel M, and have arranged in relation thereto the curved spring-arm m, which is fastened at m to the bracket h, and which may be lined upon its surface with leather, if desired, and which encircles the brake-wheel, and has at its free or movable end the projection m, which shuts into the path of the end of the lever f, so that when the lever is drawn by the coin to move the ratchet at or near the end of its movement it comes in contact with the projection m upon the curved arm at and moves it sufficiently to draw it upon the brake-wheel, and thereby make a braking action or friction of sufficient intensity to immediately overcome any momentum; and in order that this action may take place upon the shaft a at the same time, I have attached to its front end a disk, a", which is shaped substantially as shown in Fig. 4; and I have also attached to the head a springarm, a shaped substantially as herein represented, so that at the desired interval of time-- that is, at the end of the throw of the ratchet a portion, a", of the 'disk comes in contact with the spring-arm, which acts as a brake or friction.

To accurately center the nail-holder plate, tcmplet-plate, and drivers, I have attached to the arm carrying the drivers, or to the driversupporting block, a centering bar or rod, a which has a tapering or beveled end, a, and have formed in the nail-holder plate and templet-plate a recess or hole, (0, adapted to re ceive said rod or plate. See Fig. 13.) This recess, for a portion of its extent in each plate, corresponds to the shape of the rod or plate above the beveled portion but the upper portion of said holes in both plates flare or taper outwardly. The rod or plate should project below the under surface of the drivers, so that upon the reciprocation of the cross-head its end shall enter the holes in said plates and accurately center the same in relation to each other and to the drivers before the drivers enter the holes in the nail-holder plate, and by making the entrance to the said holes beveled I always insure the entrance of the rod or plate, so that if the nail-holder plate or the templetplate, or both, should be somewhat out of line they are brought in line with the drivers be fore the drivers enter the holes in the nailholder plate. This device not' only centers the nail-holder and templet, so that the holes in the nail-holder must register with the holes in the templet, but it also centers the drivers with the holes in both plates, and the two plates and the drivers are firmly bolted or locked together during the reciprocation of the machine.

The same device can be applied to the arm supporting the awls or the awl-holding block, and be used in connection with the templet alone for the purpose of securing the perfect register, if desired.

In lieu of therod or plate and holes, a yoke, a", having two arms, a, attached to the nailholder arm and awl-holding arm, or either, of the revolving head, may be used, in which case the inner or lower ends of the arms are beveled and are made long enough, and are adapted to close on each side of the nail-holder and templet plates, or either, and lock the same in position, and in Fig. 11 I have represented the nail-holder arm provided with'this centering yoke. On some accounts this construe tion is preferable to the first named, in that it does not involve the perforation of the plates, and in that it can be used nearer the, outer ends of the plates.

The top-lift holder comprises a plate, N, whichhas a bearing upon the post D, below the templet-plate, so as to swing thereon, preferably in opposition to the stress of the spring it, although this spring is not essential, so that the operator or boy can move the plate into position and hold it there during the applica tion ofthe top lift, when upon its release it will automatically move to its original position.

The top-lift holder herein shown comprises the angleplate a, the front edge of which forms a stop for the breast of the top lift, and which is movable upon the under surface of the plate N by means of the screw a The pins n which extend through holes in the downward projection a of the plate Nyhold the gage-plate true, and the curved back or end clamp or jaw, O, which is shaped to fit the end of a top lift and preferably has the outwa-rdly-extending arms 0. This jaw I prefer to support by means of the spindle which extends backwardly into a hole or recess, 0 containing a coiled spring, 0 which acts to move the spindle outwardly, so that there is always a sufficient-pressure upon the front plate, a, of

the holder to keep the top lift in place, at the same time I get a large range for adjustment to various sizes, as the back jaw will yield to any reasonable extent, and is formed to center the heel blank very accurately as the breast comes against the edge of the front plate, a, and as the curved portions bear upon IOO the curved end of thejaw, which prevents its movement in a lateral direction.

The top-lift holder is perforated when the heel is flush-11ailed,and is not when it is blindnailed, and is used either with or without a spanker. \Vhen the heel is blind-nailed, it will be desirable to use the spanker. When itis flush-nailed, however, it will not be necessary that the machine be provided with a spanker,

IIO

and in this event therevolving head willhave two armsone to support the awls and one to support the driversand the camf will be so shaped as to move the nail-holder plate a halfrevolution upon each reciprocation of the machine.

In operation, the boot or shoe is placed upon thejaclgmoved under the templetplate, and the cross-head reciprocated, the awls being in proper position. The next reciprocation of the machine moves, automatically, the drivers into position, and also the nail-holder into position over the templet, if the work is to be flush-nailed. The top-liftholder is brought into position before the reciprocation of the awls. Ifit is to be blindnailed, the top-lift the templet and forcing it and the top-lift holder downward.

The stop motion of the machine may be such that the crosshead may be provided with either two or three reciprocations, as desired. When flush-nailing is to be done,two reciprocations will be sufficient. \Vhen blind-nailing is to be done,there may be eithertwo or three, as may be required.

I do not confine myself to the specific mechanism herein described for revolving the shaft E; but may use any mechanical equivalent therefor.

Itwill be observed that by the device herein described I am enabled to automatically move the awls, drivers, and spankers, or any two of them, automatically into and out of operative position, and at the same time revolve the nail-holder plate into and out of operative position.

It is obvious that the centering and looking bolt, rod, plate, or yoke (shown in Figs. 11 and 13) may be attached to and carried by the frame of this cross-head,instead of by the revolving head,and substantially the same re sult will be obtained.

It is apparent that by the use of a centering device of this nature the fitting of the plate need not be so nice and accurate as it would be if none were used, as it is not essential that the parts he moved by their operative mechanism into perfect register, for the centering device, if they are out of line,brings them in register before the awls or drivers en ter their respective holes. Of course the shaft E may he used forrevolving the nail-holder or the head a, instead of both. It will be noticed that the templet-plate has a vertical movement, but is not moved out of operative position.

The device for locking the templet in its lowest position, thcjack, and the boot or shoe and heel-centering mechanism being fully described in said Letters Patent No. 259,687, and in the application of Henderson for pat ent, filed January 10, 1883, Serial No. 81,453, no reference to them-is necessary here.

Having thus fully described my invention,
